Hollow structure MgCo-LDH was prepared to purify Congo red (CR) and Acid red 66 (AR66) wastewater. The ZIF-67 was employed as sacrificial template to fabricate the hollow structure MgCo-LDH nanomaterial via Mg2+ simultaneous etching and subsequent coprecipitation reactions in magnesium nitrate solution. The MgCo-LDH nanomaterial provided abundant sites to adsorb the azo dyes owing to the nanosheets and hollow structures. The experimental analysis indicated that the optimal adsorption process conditions were MgCo-LDH amount of 50 mg for CR and 70 mg for AR66, adsorption time of 70 min, rotational speed of 340 r·min−1, adsorption temperature of 25 °C, and pH range of 3–9 for 15 mL of 250 mg L−1 azo dyes solution. The hollow structure MgCo-LDH had high saturation adsorption capacities of 1050.28 ± 37.34 mg g−1 for CR and 285.40 ± 5.80 mg g−1 for AR66 at the optimal condition parameters. The removal efficiencies of CR and AR66 were higher than 94.32 ± 2.09 % and 94.95 ± 1.61 %, respectively. The density functional theory calculations revealed that the azo dye molecules were adsorbed onto MgCo-LDH surface through the formation of hydrogen bonds between the hydroxyl groups and sulfonic acid groups.

MnO2 is identified as a promising supercapacitors electrode material due to its reversible Faraday reaction and great theoretical specific capacitance. However, its practical performance is hindered by poor electrical conductivity and structural instability. By incorporating Ti3C2Tx, a 2D MXene material known for its high conductivity and functional groups, the electrochemical behavior of the MnO2 composite is expected to be enhanced. This study introduces a novel method for synthesizing MnO2@Ti3C2Tx self-assembled electrodes (1, 3, 6, 9-MnO2@Ti3C2Tx composite electrodes) via a simple solution immersion technique at room temperature and ambient pressure. The state of manganese dioxide deposition can be influenced by varying the number of operations of the solution immersion technique.

When the current density is increased to 10 A g−1, the specific capacitance retention of 6-MnO2@Ti3C2Tx is 67.11 %. Furthermore, the 6-MnO2@Ti3C2Tx//Ti3C2Tx asymmetric capacitor demonstrated a maximum energy density of 30.8 W h kg−1 and a power density of 7493.3 W kg−1, maintaining a capacitance retention rate of 95.98 % (from 74.6 to 71.6F g−1) after 2000 charge-discharge cycles.
